I add a little water to the eggs before I beat them. I have heard that this helps them stay fluffy because the water cooks away and leaves the eggs looser. I also turn off the heat just a little early and cover the pan so that the eggs don't over cook. Sometimes I will mix my eggs with fried diced potato and onions and eat them in a flour tortilla with salsa. Growing up we called it "papas con huevos."
